CASTING-MACHINE.

Patented Oct. 15, 1912.

To all whom it may concern: v

'Be it known that I, FRANK ENGEL, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a certain new and useful Improvement in Casting-Machines, of which the following is a speclfication.

M v invention relates to casting machines, and the general object of the invention is to provide a simple and effective machine ating means for pressing the parts of the mold tightly together, and fifth, to provide certain details of construction hereinafter set forth.

I accomplish my objects by the mechanism illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal sectional elevation of the machine. Fig. 2 is a fragmentary transverse sectional elevation on the line 2.-2 Fig-1. Fig.'3 is a detail chiefly in vertical section illustrating a suitable methodfof connecting'l the pressing screw to the top of the-mold. Fig. 4 is an end elevation of the machine. Fig. 5 is a plan section taken on the plane just above the top of the mold. Fi 6 is a top plan view of the complete mac ine. Fig. 7 is a view of the forcing lever and Fig. 8 is an outline of the top surface of the lower mold late. f p Similar reference characters denote similar parts throughout theseveral views.

The metal to-be used in making the casting is contained within a vessel 10 mounted upon any suitable kind of legs or supporting framework 11. By preference said receptacle and its supports are inclosed within a housing 12 which may consist of sheet iron or other suitable material. The preferred means employed for heating the metal in the,

receptacle 10 is the burner 13, located beneath it-and inclosed within the housing 12.

Mounted within receptacles 10 is a cylini der 15 havin a plunger 16 slidable therein and connecte by means of a rod 17 or other suitable mechanism to a lever 18 fulcrumed on a shaft 19 rotatably mounted in stationary bearings 20. Rod 17 is by preference pivotally connected to plunger 16 and to the lower end of the offset continuation of lever18. In the preferred design said leverl is provided with a handle 21 by which it may be swung for moving the plunger 16 back and forth within the cylinder. cylinder has a port 23' so arranged that when the plunger is near thc rear end of the cylinder said port will be uncovered and vthe molten metal will flow through the port into the cylinder in front of the plunger, and when the plunger is moved forward it will close the port and force the metal in front of it up through the passage 24 into the mold.

The mold is located above the level ofthe Said v cylinder and consists, in the form of machine here selected for illustration, of two parts 25 and 26 arranged horizontally and containing the mold cavity 27. The lower part 25 is stationary, being mounted in any suitable manner upon the framework of the machine and the upper part 26 rests upon it and is adapted to be thrown back in order that the casting may be removed and the said part 26. Although the movable frame# work or memberswings about a horizontal axis, I do not, of course, limit myself to this construction. A suitable connection between said screw and the top 26 of the mold is best shown in Fig. 3, the plate 33 being1 Ibolted or otherwise secured to ,part 26 an to contact the top of said plate.

having a recess 34 adapted to receive a pin A 35 passing through the lower end of the screw. This' lower end 36 is of reduced design thereby forming a shoulder adapted As a result of ,this construction the screw is free to rotate in thev plate but when the screw is raised the plate and the top 26 of the mold will be raised with it. The screw is promeans for rotating it.

Guide rods 38 are secured to the spider` 30 parallel to the screw 32 and pass through apertures `'provided for them in the top 26 as best shown in Figs. 4 and 5. These prevent the upper mold part from rotating when the screw is rotated. When the spider is held fast in the4 position shown in full lines in the drawings any desired pressure to hold the mold closed and thus prevent leakage and the formation of fins upon the castings vmay be obtained by 'rotating they handwheel 39 in a direction to lowerthe screw 32 and .the mold part 26, carried thereby.

The spider lis adapted to be locked in lowered position by means of a rod 41 which is transversely slidable in the stationary mem'- Jbers 42 and provided with locking pins 43 adapted to pass through 'suitable apertures formed in the free legs 0f the spider and registering withv corresponding apertures A formed in the members 42. The locking rod is adapted to be shifted from one position to another to lock and release the spider by. means of a lever44 pivoted to a stationary pin 45. The construction is such that when said lever is shifted to one position the locking pins 43 will enter the registering apertures in the spider and stationary framework thus holding the spider locked in lowered position. When said lever is swung in the opposite direction the locking pins 43 will be withdrawn and the spider may be thrown back for opening the mold,

/ To facilitate the swinging of the spider and' supported arts from one position to another about t e horizontal hinge ins 3l it is desirable to provide a counterweight 47 tension of one of the hinge pins 3l and to` the oppositeA end ofthe spider by means of a pin 49. By properly proportioning the counterweight and supportmg arm the spider and its su'pptnrting parts may be so balanced that but slight exertionwill be necessary to throw the spider back when the lochngbar 41 is withdrawn, after which the spider 'and connected partswill come to equilibrium with the spider back far enough to aord free access to the mold..n

Itis understood, of course, that the above embodiment of my invention Ywas selected for the purpose of illustration only. Therefore, I.. do .not desire to limit myself to the embodiment shown and described or to the details thereof, but desire to include any suitable means for accomplishing the desired results and falling within the scope of the appended claims.

Having thus described my invention,

Letters Patent, is:

l. In a casting machine, a horizontal stationaryl mold plate, a movable mold plate adapted to rest thereon, a press associated with said movable plate, a hinge connection between said plates and a counterbalance for holding the movable plate and press up out of the way when thrown back upon the hinge. 2. In a casting machine, a horizontal stationary mold plate, a movable mold plate adapted to rest thereon, the movable plate being hinged to the stationary plate, a lock' for holding the plates one upon the other, and a press for increasing the Ipressure between the plates after they have been locked, said press carrying said movable mold plate. y

3. In a 'casting machine, a mold formed fof separable parts, a stationary frame supporting one of said mold\ parts, a movable frame hinged to said stationary frame, means for holding said movable frame stationary with respect to the stationary frame, and a screw mounted in said movable frame and carrying one vof the parts of the mold for the purpose described.

4. In a casting machine, a mold formed of separable parts, a stationary frame supporting one of said mold parts, amovable frame hinged to said stationary frame, means for holding said movable frame stationary with respect to the stationary frame, a screw mounted in said movable frame and connections between said screw and one of the moldv arts whereby the screw may be rotated in ependentlyvof said mold part' to press the samel upon and raise it from the companion mold part.
